I switched from o2 to Tesco mobile when the new iPhone 4 was released. Has anyone managed to get Tesco mobile working with Hullomail? It's not listed in the list of networks on the control panel and 'service activation code' (which sets up the call forward) that I used with o2 doesn't work. How can I manually set up the call forward for unanswered calls? Sorry if this is obvious, I searched and couldn't find anything.
